You should read a lot of Xiaomi Mi 4C reviews from different sites, but as a brand which concentrates on chargers, Tronsmart focuses on different chargers’ charging performance for Xiaomi Mi 4C.

In the following analysis, you will see we test with regular 5V/2A charger ( Oneplus 2 original charger, no quick charge), and original xiaomi charger (support quick charge 2.0). Also tronsmart charger(support quick charge 2.0).

We are the first time to see the 12w quick charger. We even doubt if this is certified quick charge at first, because, Our quick charge are all 18W, support 5V/2A, 9V/2A, 12V/1.5A. After check on qualcomm site, we found, this charger is really certified by qualcomm, xiaomi should consider the cost and use this 12w solution, In this area, more volt means more cost.

Now, let’s do some real test to check the performance:

1)Test with the above xiaomi 12w quick charger:

Total Charging time from battery 0% to 100% is 2 hours and 7 mins with the original charger.
When we first connect the charger, the Mi 4c and the charger have the “communicate” and directly change the charging volt from 5V to 9V. and in the whole charging time, the volt is always keep in around 9v to make sure get the fastest charging speed.

In the first 10 mins, it can charge the Mi 4c from 0%-14%, it’s fast! and after 30 mins, Mi 4c get 34% battery. It take about 1.5hours to get 90% battery, but for the rest 10%,it take another 30 mins.

The charging current is becoming smaller as the battery is full.

2)We use the original charger from Oneplus 2 to test Xiaomi Mi 4C(Regular 5V/2A 10W charger, no quick charge support)

The total charging time for Mi4c from 0%-100% is about 2H 43min.
The original adapter of OnePlus Two is built-in standard 5V/2.0A output power, don’t support Quick Charge. So the charger just can give 5V volt to Mi 4c.

In the first 10 mins, the mi4c just get 9% battery, and 30mins later, it has 26% battery. Which is slower than the xiaomi’s quick charger.

3) Test with Tronsmart QC 2.0 Wall Charge (18W)
We are a big surprised by the result, at first we thought our 18W charger should make it faster than the xiaomi’s 12w charger, however, from he above test, we found, the charging time is almost the same, Xiaomi must limit the total watt which Mi4c can hold. Our charger can successfully “communicate” with Mi4c, and change the charging volt to 9V, however, the current can’t go up than 1.2A. total watt is still lower than 12W.

For the same charger, we test in zenfone 2, it can give 16w. so it’s not our charge problem, but Xiaomi make some limit.

4)Test with Tronsmart Type-C Car Charger
Because our ammeter don’t have type c female port, we can’t read the volt/current in the charging, but we can see the charging time, and battery change.
Total charging time with our type c for mi 4c is just 1 hour 58mins. It’s the best result in all of test!
5)Test OnePlus Two with the OP2 original charger
Though it don’t support quick charge 2.0, the battery is also bigger(3300mA) than Mi 4C(3080mA) , the total charging time for Oneplus 2 just 2 hour 10mins. Almost same as the XiaoMi Mi4C (2 hours 7 mins) , which claim to support quick charge 2.0 technology.

Conclusion

XiaoMi 4C is the few device which support Type C and Quick Charge 2.0 technology together.

The Charging performance is not as good as we expected, thought 2 hours 7 mins fully charge is not a very bad result, but we are very upset to see xiaomi did some trick in the charger, even they state it support quick charge 2.0, however, the total power just 12W.

So the conclusion must be, that the TWO charges to 100% "faster" cus of the bigger battery.. Ergo if both phones had the same size battery, the two would reach 100% first, even though it does not support QC.

Yes, in our test, we find that Xiaomi Mi 4C make some limit. Xiaomi should consider the cost and use this 12w solution. In this area, more volt means more cost.

I have recently received my 2 and have been really impressed with how quick it charges: I have come from a HTC sensation (I broke my nexus 5) and that took longer to charge than its actual battery life (cause batteries die over time but still!). 2 hours 10 is amazing for that size battery! Very happy

Hmmm...just one question here...why didn't you post this analysis on xiaomi forum but post it here first?
I found this very odds since you posted on one forum only cause this analysis is focusing mainly on Mi4c charging ability not OnePlus Two...perhaps you guys loved OnePlus Two so much that you try to make Mi4c look bad and afraid to show your analysis to Xiaomi forum...Xiaomi might have an answer to why they have limited the charging ability on Mi4c so please shares your analysis there too and find out why...
